FAQ

What is a cron expression?

A cron expression is a string of 5 fields (minute, hour, day, month, weekday) that defines a schedule. Used in Linux crontab, CI/CD, and cloud schedulers.

What does */5 mean?

*/5 means "every 5 units." For example, */5 in the minute field means every 5 minutes (0, 5, 10, 15, ...).

Is 0 or 7 Sunday?

Both 0 and 7 represent Sunday in most cron implementations. We use 0 for Sunday by default.
